ADJUSTABLE STOOL.

Application filed February 6,1925. Serial No. 7,232.

This invention relates to a stool adapted to be used in connection withatable, work bench, kitchen cabinet or the like, and the principalobject of the invention is: to pro-' vide a seat which can be moved froma posi-. tion where it is used as such to a position below a table orcabinet, or where it will be out of the way from its position as a seat;a further object is to provide a seat or stool which can be adjusted inheight; another object is to provide a swinging support from which thestool may be easily disengaged whenever desired; a still further objectis to provide a mounting for the seat and stool 'which automaticallyraises it from engagement with the fioor as soon as'a person arisesfroin the seat. Other objects will appear hereinafter.

In the accompanying drawing, Fig. 1 illustrates the invention as appliedto an ordinary table or cabinet; Fig. 2 is an enlarged view of one ofthe mounting members; Fig. 3 is a section of a post clamp; and Fig. 4 isa detail of the supporting post.

In carrying out this invention a hlnge 5 is secured by fastening screwsor the like to a vertical support or post 6 of a table or cab net 7usually having a lid or top 8. A swinging support 9 has hinged parts 10at one end which register with the fixed hlnge member 5 so that apivoting bolt 11 can be Inserted for fastening them together. At theother end of the supporting member 9 are spaced.

hooks 12 with corresponding notches 13, normally disposed in an uprightor vertical position.

The stool proper comprises a tubular stem 1& with a stamped base plate15 at the lower end, and a collar member 17 at the upper end which isthreaded or pressed firmly into the.

end of the stem 14, and provides a continuous abutment or head 18 whichprojects outwardly beyond the tubular stem 14. A supporting sleeve 19 isprovided which fits loosely around the stem 14 adjacent the top thereofheld in place by a pair of spacing rivets 20 which hold the extremities21'of the member a slight distance apart equal at least to the thicknessof the hooks 12 of the mounting member 9. The rivets 20 are the samedistance apart as the notches 13 so that the supporting stem 14 willslide freely through the sleeve 19 but without any undue loosenesstherein. Interposed between the upper end of the sleeve and theprojection 18 of the collar 17 and surrounding the stem 14; is a spring22 which tends to raise the supporting stem from the sleeve, and thehinging support is-mounted atsuch a height that normally the base plate15 of the stem height of the stool may be adjusted by rotating the seatand the baseof the stool is always ralsed free from engagement with thefloor as soon as a person arises therefrom by the 14: will be raisedfrom the floor a slight disaction of the-spring 22. The base plate ismade sufficiently large so that the stool will stand by itself so thatit does not rock or wabble when in use besides being supported by thesleeve 19 and the supporting member 9. If it is desired, the stool maybe easily disconnected as a unit from the supporting member 9 by simplylifting the sleeve 19 from engagement with the notches 13 of the hooks12. The stool may then be used separately and the base 15 issufficiently large to hold it in upright position on any substantiallyfiat or plane surface. The supporting member 9 may also be disconnectedfrom'the hinge member 5 by simply removing the pivoting bolt 11.
